Description. 2.0872 (CuNi10Fe1Mn) cupronickel is a 90% copper, 10% nickel alloy that also contains small but important additions of iron and manganese to enhance overall strength corrosion resistance. This, combined with high ductility and toughness, makes it a popular grade for marine, architectural and industrial applications.
The density of copper (8.93 kg/dm 3 at 20 °C) varies only slightly with increasing nickel content (density of nickel at 20 °C = 8.9 kg/dm 3) and is 8.9 kg/dm3 for all Cu-Ni alloys specified in DIN 17 664. This aspect can also be seen in Table 7 with the physical properties of the Cu-Ni resistance alloys to DIN 17 471.
